General Data for all Zeron ® 100 MMA Electrodes
3 hermetically sealed ring-pull metal tins per carton, with unlimited shelf life. Direct use from tin is satisfactory
for longer than a working shift of 8h. Excessive exposure of electrodes to humid conditions will cause some
moisture pick-up and increase the risk of porosity.
For electrodes that have been exposed:
Redry 200 – 300°C/1-2h to restore to as-packed condition. Maximum 400° C, 3 cycles, 10h total.
Storage of redried electrodes at 50 – 200°C in holding oven or heated quiver: no limit, but maximum 6 weeks
recommended. Recommended ambient storage conditions for opened tins (using plastic lid): < 60% RH, > 18°C.
